Which of the following hormones stimulates the secretion of milk from female ?

Options

A. Oxytocin
B. Progesterone
C. LH
D. Prolactin

Answer

To answer the question regarding which hormone stimulates the secretion of milk from females, we can follow these steps:

### Step 1: Understand the Role of Each Hormone
- **Progesterone**: This hormone is primarily involved in maintaining the menstrual cycle and supporting pregnancy. It does not directly stimulate milk secretion.
- **Luteinizing Hormone (LH)**: This hormone is secreted by the anterior lobe of the pituitary gland and is mainly responsible for triggering ovulation. It does not play a role in milk secretion.
- **Prolactin**: This hormone acts on the mammary glands and is crucial for the development of breast tissue and the production of milk. It prepares the mammary glands for lactation.
- **Oxytocin**: Known as the "love hormone," oxytocin is released during childbirth and plays a significant role in promoting lactation by stimulating the ejection of milk from the mammary glands.

### Step 2: Identify the Correct Hormone
From the analysis:
- Prolactin is responsible for the production of milk.
- Oxytocin is responsible for the ejection of milk during breastfeeding.

### Step 3: Conclusion
The hormone that stimulates the secretion of milk from females is **Prolactin**. While oxytocin plays a role in the process of lactation, it is prolactin that primarily stimulates milk production.

### Final Answer
**Prolactin** is the hormone that stimulates the secretion of milk from females.
